<div style="margin-left: 0px;">
The <b>BOOST_PP_LIST_APPEND</b> macro appends two <i>lists</i>.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_LIST_APPEND</b>(<i>a</i>, <i>b</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>a</dt>
<dd>
The first <i>list</i>.
</dd>
<dt>b</dt>
<dd>
The second <i>list</i>.
</dd>
</dl>
<h4>Remarks</h4>
<div>
This macro appends two lists.
For example, if <i>a</i> is (<i>1</i>, (<i>2</i>, (<i>3</i>, <b>BOOST_PP_NIL</b>))) and <i>b</i> is (<i>4</i>, (<i>5</i>, <b>BOOST_PP_NIL</b>)),
this macro will expand to:
<div>
(<i>1</i>, (<i>2</i>, (<i>3</i>, (<i>4</i>, (<i>5</i>, <b>BOOST_PP_NIL</b>)))))
</div>
</div>
<div>
Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>.
There is no longer any such restriction.
It is more efficient, however, to use <b>BOOST_PP_LIST_APPEND_D</b> in such a situation.
